There are no validated algorithms to predict choledocholithiasis in this group of patients. <b><i>Aim:<\/i><\/b> The aim of this study was to evaluate the performance of the choledocholithiasis diagnostic score proposed by the American Society for Gastrointestinal Endoscopy, in patients with acute cholecystitis. <b><i>Material\/Methods:<\/i><\/b> A retrospective cross-sectional study, covering a 4-year period at a secondary care hospital, was performed. All patients with an encoded diagnosis of acute cholecystitis and with at least one of the following procedures were included: endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound, magnetic resonance cholangiopancreatography, and intraoperative cholangiography. <b><i>Results:<\/i><\/b> Among 4,369 patients with the diagnosis of acute cholecystitis, 40 (0.92%) had clinical or sonographic suspicion of choledocholithiasis. Their mean age was 68.1 \u00b1 15 years, and 22 (55%) were men. Thirty-one of the patients included (77.5%) had a high risk of choledocholithiasis, and 9 (22.5%) had an intermediate risk. In 16 (51.6%) of the 31 patients with a high risk, the diagnosis of choledocholithiasis was confirmed. In 2 (22.2%) of the 9 patients with an intermediate risk, the diagnosis of choledocholithiasis was also confirmed. The high risk score for choledocholithiasis had a positive predictive value of 52% and a sensitivity of 89%. The intermediate risk score for choledocholithiasis had a positive predictive value of 22% and a sensitivity of 11%. <b><i>Discussion and Conclusions:<\/i><\/b> Suspicion of choledocholithiasis in patients with acute cholecystitis was a rare event (<1%). The sensitivity of the high risk score was approximately the same as found in published series with patients with suspected choledocholithiasis overall (86%), while the positive predictive value was substantially lower (52 vs. 79.8%). Therefore, in patients with acute cholecystitis and suspected choledocholithiasis, this score should not be used to screen for common bile duct stones, and a sensitive method should be used prior to ERCP.<\/jats:p>","DOI":"10.1159\/000479973","type":"journal-article","created":{"date-parts":[[2017,9,14]],"date-time":"2017-09-14T21:01:19Z","timestamp":1505422879000},"page":"24-29","source":"Crossref","is-referenced-by-count":12,"title":["Performance of the Choledocholithiasis Diagnostic Score in Patients with Acute Cholecystitis"],"prefix":"10.1159","volume":"25","author":[{"given":"Catarina","family":"Gouveia","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5152-2453","authenticated-orcid":false,"given":"Rui","family":"Loureiro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rosa","family":"Ferreira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandre","family":"Oliveira Ferreira","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ant\u00f3nio Alberto","family":"Santos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Pia Costa","family":"Santos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7978-4287","authenticated-orcid":false,"given":"Carolina","family":"Palmela","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00edlia","family":"Cravo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2017,9,15]]},"container-title":["GE - Portuguese Journal of Gastroenterology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/479973","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/479973","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/479973","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:50:48Z","timestamp":1745427048000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000479973"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,9,15]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2018,1,18]]}},"URL":"https:\/\/doi.org\/10.1159\/000479973","archive":["Portico"],"relation":{},"ISSN":["2341-4545","2387-1954"],"issn-type":[{"type":"print","value":"2341-4545"},{"type":"electronic","value":"2387-1954"}],"subject":[],"published":{"date-parts":[[2017,9,15]]}}}
